RE: Need help for IMAC, & converted engine plane?
Harry,
Im glad your starting in IMAC. It is a great thing to get involved in. I would assume that the 46cc would be enough on the plane as long as you can keep it light. I know I have flown the QQ 85" yak on a DA 50 and it was insane power so if you can keep the weight to within 15-16 pounds you should have enough power for the first few classes in IMAC.
